Title: Production of fresh water from sea water
Inventor: DOMEN JEAN PAUL
IPC: C02F1/14
Filed: 1997-06-13
Abstract: Fresh water is produced from sea water using a solar powered still. The still vessel is made mainly from a two-layer flexible material. Its outer layer is a dark coloured, strong, impermeable membrane (36a) with good resistance to ultra-violet light and salt water. This is lined on one side by a hydrophilic material (38a), such as non-woven cellulose, which has a good resistance to salt water. The two materials are joined by a suitable adhesive. The still includes one evaporation chamber (12) and two condensation chambers (14, 30) with air circulated through them by an electric fan (28), keeping the installation inflated and at a slight positive pressure. Sea water is fed by gravity through a pipe (40) to the hydrophilic layer lining the evaporation chamber where it is heated and evaporation occurs. Solar heating is enhanced by a transparent thermal isolating coating (46b) above the chamber. Vapour passes (24) from the evaporator to the first condensing chamber, without sea water being able to pass, and then passes to the second condensation chamber. The outer wall of this chamber is kept cool by a supply of sea water (58). Fresh water and concentrated brine are collected separately (54,56 respectively). Also claimed is the above still.

Title: Electric current supply system with multiple sources with redundancy
Inventor: KURUMA AKIO
IPC: H02J3/38
Filed: 1998-02-18
Abstract: The electric supply system has multiple sources of supply and a controller that is connected to the supplies and which adjusts the current supplied to an external load. The positions of the connections are attributed respectively to the individual supplies as addresses. The supplies send the connection positions in the form of connection position signals to the controller. The controller determines the number of supplies available on the basis of the connection positions and adjusts the current from each on this basis. Each of the supplies delivers an anomaly signal to the controller so the controller knows which supplies are not functioning correctly, and can adjust the other supplies accordingly.

Title: Methode de mesure rapide de l'indice de resistivite d'echantillons solides tels que des roches
Inventor: FLEURY MARC
IPC: G01N33/24
Filed: 1998-07-24
Abstract: - Méthode et dispositif de mesure de la courbe de l'indice de résistivité (Ir) d'un échantillon solide tel qu'un échantillon géologique indépendamment de la courbe de pression capillaire (Pc).- On réalise des mesures de l'impédance complexe à plusieurs fréquences, de l'impédance d'un échantillon soumis à une pression radiale de confinement, au cours d'opérations de drainage ou d'imbibition d'un premier fluide initialement saturant, au travers d'une membrane semiperméable, perméable à ce premier fluide, disposée à une première extrémité d'une cellule de confinement, ceci par injection d'un deuxième fluide sous pression à son extrémité opposée. On applique un ou plusieurs paliers de pression d'injection et, on mesure les variations continues de l'indice de résistivité (Ir) en fonction de la variation de saturation moyenne (Sw) sans attendre que s'établisse les équilibres capillaires. On utilise pour cela des électrodes plaquées contre l'échantillon à sa périphérie, ces électrodes ayant une extension longitudinale en rapport avec la longueur de l'échantillon et étant connectées à un impédancemètre. On applique un courant électrique au travers de l'échantillon et on détecte les variations de la différence de potentiel électrique qui en résultent. Les mesures de l'indice Ir peuvent être effectuées dans un temps relativement court : de quelques heures à quelques jours selon la perméabilité de la carotte. - Applications à l'étude de zones souterraines par exemple.
